DETAILED DESCRIPTION

While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

In the following detailed description for purposes of explanation and not limitation, exemplary embodiments disclosing specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one having ordinary skill in the art that the present invention may be practiced in other embodiments that depart from the specific details disclosed herein. In other instances, detailed description of well-known devices and methods may be omitted so as not to obscure the description of the present invention.

In medicine and therapeutic treatments, a catheter is a tube that can be inserted into a body cavity, duct, or vessel. Catheters thereby allow drainage, injection of fluids, diagnostic agents, and/or medicine, or access by surgical instruments. In most uses, a catheter is a thin, flexible tube (i.e. a “soft” catheter) and, in some uses, a larger, solid tube (i.e. a “hard” catheter). Various catheter tip designs are known including coudé tips, stepped tips, tapered tips, over-molded tips, split tips, and so forth. Catheters may include various accessories such as molded components, over-molded sub-assemblies, connecting fittings such as hubs, extension tubes, and so forth.

During and after use, catheters can be colonized by micro-organisms if the catheters come in contact with the user's unsterilized skin, specifically on the perineum and the tip of the urethra. The colonizing micro-organisms can multiply and form a biofilm layer within 24 hours of catheter use, during which they are metabolically active and viable. Catheters contaminated with said microorganisms are known to cause negative health outcomes such as UTIs when used without sterilization. It is known that while there are homemade means to sterilize catheters such as rinsing the used catheter followed by submerging in isopropyl alcohol for a five-minute duration, inconsistent rinsing and inappropriate post-sterilization storage causes re-contamination of catheters by exposing them to potential colonization by micro-organisms and leads to negative health outcomes for the user.

The invention relates to enabling medical device users (e.g., catheter users) concerned with sterilizing their products from bacteria and other microorganisms to use a portable germicidal device that utilizes radiation to sterilize the medical product(s), safely shields the user from radiation or other exposure during such sterilization, and provides sterile storage of the catheter or other medical product until needed. Moreover, the devices, systems, and methods according to the invention preferably provide increased standardization for sterilizing catheters or other products to reduce the risk of inadequate and/or inconsistent sterilization.

One aspect of the invention relates to systems and/or apparatuses capable of sterilizing medical products, preferably catheters, or other products using radiation. The apparatus of the present invention can be efficiently configured and designed to provide sterilization of the surfaces of a medical device by emitting radiation in a range sufficient and effective to destroy contaminants including pathogens and microorganisms. According to one preferred embodiment, radiation emitting diodes are placed in an array such that radiation is emitted into the interior of the apparatus enclosing the medical device for sterilization. The array may be configured linearly, circularly, or rectangularly to form a matrix of diodes and may be located on, within, or behind the interior wall of the sterilization chamber. Preferably, the systems and/or apparatuses can repeatedly sterilize medical products (e.g., catheters) without damaging them.

One preferred embodiment relates to a device comprising an interior chamber adapted to enclose a medical device and adapted to irradiate the medical device with radiation to sterilize the medical device.

Another embodiment relates to an apparatus for sterilizing a medical device, the apparatus comprising: (a) one or more walls defining an interior for containing radiation and for enclosing the medical device; (b) at least one radiation source comprising a plurality of radiation emitting diodes, wherein the diodes are positioned to emit radiation within the interior; (c) a power source capable of providing energy to the diodes; and (d) one or more openings adapted to provide a seal between the interior and external environment when closed.

Another aspect of the invention relates to methods of sterilizing one or more medical devices or other products using radiation. One embodiment of the invention relates to a method for sterilizing a medical device using ultraviolet (UV) radiation comprising: (a) enclosing the medical device in a chamber; (b) sealing the chamber; and (c) irradiating surfaces of the medical device with UV radiation thereby destroying biological contaminants on the surfaces of the medical device.

Another embodiment of the invention relates to a method for sterilizing a medical device using microwave radiation comprising: (a) enclosing the medical device in a chamber; (b) sealing the chamber; and (c) irradiating surfaces of the medical device with microwave radiation thereby destroying biological contaminants on the surfaces of the medical device.

Another embodiment of the invention relates to a method for sterilizing a medical device using thermal radiation comprising: (a) enclosing the medical device in a chamber; (b) sealing the chamber; and (c) irradiating surfaces of the medical device with thermal radiation thereby destroying biological contaminants on the surfaces of the medical device.

Another aspect of the invention relates to a system comprising at least one apparatus or device as described herein and one or more additional components to facilitate the convenient sterilization of one or more medical products using radiation.

The foregoing has outlined some of the aspects of the present invention. These aspects should be construed strictly as illustrative of some of the more prominent features and applications of the invention, rather than as limitations on the invention.

Many other beneficial results can be obtained by modifying the embodiments within the scope of the invention. Accordingly, for other objects and a full understanding of the invention, refer to the summary of the invention, the detailed description describing the preferred embodiment in addition to the scope of the invention defined by the claims and the accompanying drawings. The unique features characteristic of this invention and operation will be understood more easily with the detailed description and drawings. It is to be understood that the drawings are for illustration and description only and do not define the limits of the invention.

It is known that in some settings and some circumstances, radiation of various wavelengths can inactivate microorganisms such as bacteria, virus, fungi, protozoa, algae, and so forth using electromagnetic waves of various wavelengths and bands, including ultraviolet light, thermal radiation, and microwave radiation. Ultraviolet light is typically characterized in the following wavelength bands: ultraviolet-C (UVC) having a wavelength of 100 to 280 nm, ultraviolet-B (UVB) having a wavelength 280 to 320 nm, and ultraviolet-A (UVA) having a wavelength of 320 to 400 nm. Microwaves are characterized with a wavelength between 1 mm to 1 m, where most conventional microwave ovens operate near a 12 cm wavelength (2450 MHz). Thermal radiation is a broadband type of emission that isn't typically characterized by its wavelength band and most often referred to as heat. In all cases, these types of radiation are often used to sterilize surfaces and/or objects in hospital settings.

It is noted all forms are radiation are dangerous for humans with substantial exposure with outcomes dependent on the wavelengths emitted. Dependent on the wavelength, UV can be absorbed by DNA extremely well causing DNA to mutate, which is the primary mechanism used to inactivate microorganisms through UV. However, this mechanism also applies to humans, where high human exposure to UV causes radiation sickness, resulting in symptoms such as eye irritation and reddening, skin irritation, nausea, fever, disorientation, hair loss, cancer, and, in extreme cases, death. Microwaves and thermal radiation can cause molecules such as water to vibrate and heat up creating hydrothermal pressure within a cell body, causing damage to the cell wall, breakage of genomic DNA, and thermal coagulation of cytoplasmic proteins resulting in cell death and/or inactivation. Again, this phenomenon applies to human cells as well and high exposure to microwave and/or thermal radiation can result in burn injuries and co-morbidities that can result in death. For these reasons, high doses of any radiation must be prevented from striking humans.

One or more of the inventions relate to improved apparatuses, systems, and methods for sterilizing medical or other products using radiation and similar energy.

One aspect of the invention relates to apparatuses having an interior or inner chamber adapted to sterilize a medical device, preferably a portable device adapted to be used by individuals, preferably at home or at their convenience.

Another embodiment relates to a device comprising an interior chamber adapted to enclose a medical device and adapted to irradiate the medical device with radiation to sterilize the medical device.

Another embodiment relates to an apparatus for sterilizing a medical device, the apparatus comprising: (a) one or more walls defining an interior for containing radiation and for enclosing the medical device; (b) at least one radiation source comprising a plurality of radiation emitting diodes, wherein the diodes are positioned to emit radiation into the interior; (c) a power source capable of providing energy to the diodes; and (d) one or more openings adapted to provide a seal between the interior and external environment when closed.

Referring now to the Figures, there is shown a variety of embodiments of intermittent urinary catheters and catheter systems. Additionally, each of these variations may have a variety of optional equipment, components, and features associated therewith.

FIG. 1A shows a cross sectional view of one embodiment of an apparatus 100 according to the invention. As illustrated, the apparatus 100 includes a sterilization chamber 101 having interior 106 and the medical device 114 positioned within the interior 106.

The interior 106 preferably comprises a top wall 102, a bottom wall 103, opposing side walls 104 and opposing side walls 105 (FIG. 1B), which define the interior 106 of the chamber 101. Alternatively, interior 106 can be configured with curved inner wall (e.g., egg-shell shaped with curved sides and top and bottom). The sterilization chamber 101 is protected by housing 107. As depicted, a preferred embodiment of the invention is a rectangular block with rounded edges where one end has one or more openings and has one or more switches 131 on one of the exterior walls. Furthermore, there is a structural skeleton 108 that is used to insulate the interior chamber 101 from the housing 107, provide additional rigidity, and enhance heat dissipation.

Preferred embodiments are portable. The height/length 127, thickness 128, and width 129 are denoted in FIGS. 1A and 1B. Preferably, the overall dimensions of the apparatus housing are: height 127 of 5″ to 18″ (preferably 6″ to 16″), length 128 of 1.5″ to 6″ (preferably 1.5″ to 5″), width 129 of 1″ to 6″ (preferably 1.5″ to 5″). Preferably, the dimensions for the interior are: Height of 4″ to 14″ (preferably 5″ to 12″), length of 0.75″ to 4″ (preferably 1″ to 3″), width of 0.75″ to 4″ (preferably 1″ to 3″).

According to preferred embodiments of the present invention, one or more walls of the interior of the chamber are radiation reflective as to distribute radiation throughout the interior of the chamber. The spectral reflectance of this chamber should be no less than 80% reflective to the emitted radiation wavelengths. Preferably, the interior wall comprises aluminum.

The apparatus comprises multiple openings that can open and close: one to insert the medical device 114 into interior 106 and one can be opened to allow access to a cavity 118 in the housing used to store replaceable medical or cleaning supplies, preferably sterile gloves, isopropyl alcohol, or betadine. Preferably, the apparatus includes lid 138 that pivots about a hinge 115 allowing the lid to open or close. A sealing gasket 112 provides a releasable hermetic seal allowing sterile storage of the medical device 114 within interior 106. Once sealed, a magnetic lock 119 is used to lock the apparatus during operation and storage. A medical device 114 is shown positioned within the chamber with anchored support 113 on the side wall 104.

The closed interior 106 compartment can substantially eliminate stray energy from escaping the interior 106 while eliminating fluid exchange with environment. Any suitable UV reflective material may be incorporated in the composition of the interior 106 wall or surface during manufacture or assembly. Polished aluminum could be utilized as a surface material because of its high reflectivity. The sealing gasket 112 is made of UV stable material such as silicone.

Disposed within the apparatus 100 are individual ultraviolet light emitted diodes (UVLEDs) 109 placed in an array such that radiation is emitted into the interior. Preferably, the diodes have a peak emission wavelength range of 240 to 320 nm and more preferably 285 nm. Preferably, the diodes have a radiant flux range of 0.1 mW to 100 mW. The sterilization chamber 100 of the present invention can provide the necessary decontamination and sterilization measures to effectively ensure a 5-log reduction [99.999%] of any residual biological contaminants on the exposed or hard-to-reach crevices of a medical device. Preferably, multiple UVLEDs 109 are arranged on or along one or more of the walls and there is sufficient space to the opposing wall to allow reflection of the irradiation allowing irradiation of multiple surfaces of a target consistently. For example, preferably LEDs 109 are recessed into the walls of the interior 106 and configured to emit UV into the interior 106. A heat sink 116 is affixed to the UVLEDs to improve heat dissipation during operation. In the depicted embodiment, the heat sinks are applied to the outer surface of walls comprising interior 106 and in direct contact with the non-emitting surface of the UVLEDs 109. In another embodiment, one heat sink may be applied to an array of diodes. In another embodiment, one heat sink may be applied per wall of the sterilization chamber.

A power supply 110 provides energy to the UVLEDs 109 and preferably comprises an internal supply of energy such as a rechargeable battery. A microcontroller 111 is used to control operation of apparatus electronic components such as the UVLEDs 109. This microcontroller 111 receives information from a switch 131 which enables to the user to open and close the magnetic lock 119. The microcontroller also receives information from a UV sensor 122, humidity sensor 123, temperature sensor 124, light sensor 125, and pressure sensor 126. This information is used to determine whether the apparatus is in operation and whether the apparatus is functioning out of expectation. For instance, visible light should not be detected within the chamber once the chamber is sealed and locked. If the switch is activated and visible light is detected by the light sensor, the microcontroller will not allow the UVLEDs to operate. Other events include but are not limited to rapid temperature swings, rapidly decreasing humidity during operation, detected pressure lower than atmospheric pressure.

A serial code reader 137 is used wherein a user would scan a serial code related to the medical device prior to sterilization to track the number of times the medical device was irradiated in the apparatus. A memory card 121 is used to log this event data. A wireless transmitter 130 is used to transmit this data to an external source such as a cellphone or a laptop.

Current operation of the apparatus can be viewed through the indicator LED 133. For example, when the unit is not in operation and not sealed, the LED would be off. When the unit is sealed but not in operation, the LED would shine blue. When the unit is sealed and in operation, the LED would pulse purple. When the unit is sealed and finished with operation, the LED would shine green.

Potting material 117 is used to encapsulate electronic components in order to mitigate radiation exposure, improve heat dissipation, and resist shock and vibration. As depicted, the potting material 117 is applied as insulation in the volume or space between the housing 107 and sterilization chamber 106, for example where electronic components are housed. Additional insulating material may be used to fill the cavities between the exterior walls of the apparatus and the sterilization chamber to further insulate the apparatus interior from the exterior environment.

As depicted in FIGS. 1A and 1B, the apparatus 100 further comprises a textured grip 135 to provide an ergonomic handle, allowing safer handling of the apparatus. The apparatus further comprises an exterior bumper guard 134 around the housing at each end to protect the apparatus from falls and shocks.

As depicted in FIGS. 1A and 1B, a micro fluid pump 136 is used to pump fluid into and out of the chamber. In this embodiment, the fluid pump 136 is used to pump a mixture of water, hydrogen peroxide, and silver particles to enhance sterilization. It is known that hydrogen peroxide and silver particles enhance DNA inactivation when using in conjunction with UV radiation. After sterilization, the micro fluid pump 136 will remove remaining fluid within the chamber. Micro fluid pump 136 can either be included within a unit that is attached to the apparatus as in FIG. 1A or integrated within the apparatus (e.g., enclosed within housing 107, preferably adjacent interior 106) as in FIG. 1B. For example, the apparatus may have a port to connect to a fluid pump to provide fluid to the interior chamber.

According to one embodiment of the present invention, the exterior of the apparatus housing further comprises one or more external supports, legs, tabs or grips on the exterior surface of the housing to allow the unit to stand upright and in a stable manner.

Another preferred embodiment relates to an apparatus for sterilizing surfaces of medical devices from contamination by microorganisms, the apparatus comprising: one or more walls which define an interior chamber for containing UV radiation such that the interior chamber can be proportionally sized to enclose target medical device requiring sterilization; a housing for the interior chamber with sufficient space to accommodate electronic circuitry and components; a source of radiation comprising a plurality of LEDs such that the LEDs can be positioned in relation to the interior chamber and/or the one or more walls; a power supply providing energy to the LEDs such that the LEDs emit UV radiation into the interior chamber; and one or more seals such as a gasket or O-bearing positioned to provide a hermetic seal for the interior chamber, preventing fluid and microorganism exchange between the interior chamber of the apparatus and the exterior environment, so that the plurality of UV LEDs substantially irradiate all surface areas of the target medical device with UV radiation and the apparatus further provides sterile storage of medical device while being sterilized and thereafter.

FIG. 2 shows an external view of an apparatus with a medical device according to one embodiment and a user hand for scale. As illustrated, the system 200 includes the sterilization apparatus 201, medical device 206, and a user hand 202. The sterilization apparatus 201 is shown in a user hand 202 to demonstrate the scale of portability of this embodiment, though it is again noted that this is for the purposes of explanation and not a limitation. As illustrated, a medical device 206 may be removably positioned to and from the interior of the sterilization apparatus 201. External switches 203 control the opening and closing through electrical controls. A sealing gasket 204 is used to create a hermetic seal to maintain a sterile interior environment before, during, and after irradiation. A textured grip 205 is positioned to allow for optimal grip for users with low hand dexterity and grip strength. Slippage grips 208 are used to reduce slippage when the apparatus is placed on a smooth surface. Preferably, both the textured grip and slippage grips are to be made of a durable and malleable material such as a silicone. Instructions 207 are placed on the exterior to guide the user to the correct procedure. In this preferred embodiment, the instructions are printed though alternatively, the instructions may also be preferably embossed. Personal identification 209 is printed on the outside to allow users to identify their apparatus. Alternatively, the personal identification may also be preferably embossed.

In preferred embodiments of the present invention, a holster or clip (not shown) may be included to allow user to carry or mount or clip the apparatus 100 on their person or an object such as a wheelchair, as shown in FIG. 3 (discussed below).

According to the invention, the apparatus can be designed to be portable (both small and light) and easy to use.

FIGS. 10-14 illustrate another embodiment of methods and systems for urinary catheterization, urinary catheter sterilization, and combined data acquisition and deposition. Specifically, FIGS. 10-14 illustrate an at-home sterilization and data acquisition and deposition device including a housing having an opening or series of openings for receiving up to six medical devices, a sterilization chamber formed within the housing that is lined with sterilizing radiation reflecting material, and several sources of sterilizing radiation disposed within the sterilization chamber for sufficient emission of radiation to achieve a significant log reduction of any pathogens present on the medical devices, and an RFID scanner and sensor suite configured into the housing that prevents sterilization of non-system components, radiation emission into the environment, and that can pair with a user's mobile device. An individual catheterization system includes an at-home sterilization and data acquisition device, a software-enabled analysis of data acquired through the system, a set of accessories to enable proper lubrication, cleaning, and radiation-based sterilization of medical devices, and a set of RFID-enabled medical devices designed to facilitate sterile emptying of the bladder by providing a tactile interface that prevents direct contact between the individual and the parts of the medical devices that enter the individual's body.

Intermittent urinary catheters are essential medical devices that are typically used by individuals with neurogenic bladder and lower urinary tract symptoms to manually empty the bladder of urine if it is neurologically or physically obstructed. While the use of these catheters is oftentimes considered to be the healthiest short- or long-term method for bladder management, especially when compared to alternatives like suprapubic or indwelling catheters, improper use of these catheters can result in contact contamination of the catheter, the subsequent introduction of pathogens to the bladder, and an overall substantially higher urinary tract infection [UTI] risk for the individual. Additionally, improper use of the catheter is extremely likely given the overall lack of ergonomic consideration in the design of the catheter in the case of standard, low-cost catheters. While easier-to-use catheters do exist, they do so at a price point that is often 5-7× the price of standard, low-cost catheters. Insurance coverage of these easier-to-use catheters is limited, and reuse is prevalent to offset the financial cost to the individual. Moreover, compliance with clean catheterization guidelines is generally low due to their onerous nature and requirement of a vast kit of parts that are difficult, if not impossible, to transport.

A need exists for an easy-to-use and affordable catheterization system that mitigates the UTI risk associated with the use of today's catheters.

Specifically, as illustrated in FIGS. 10-12 , a low-footprint sterilizer 1000 may sterilize up to six catheters 1100, 1200 and insertion aids 1106, 1206 simultaneously using UVC-bulbs 1003. Each catheter 1100, 1200 and insertion aid 1106, 1206 may be sandwiched by the UVC bulbs 1003 to facilitate adequate log reduction/sterilization of the catheter 1100, 1200 between uses. The catheters 1100, 1200 and insertion aids 1106, 1206 may each fit into an individualized tray 1007 within the unit 1000. Alternatively, the catheters 1100, 1200 and insertion aids 1106, 1206 may be placed into resealable UVC-transparent plastic bags to facilitate their sterile transport after removal from the sterilizer 1000 after the completion of a sterilization cycle. Specifically, an at-home sterilization and data acquisition and deposition device 1000 including a housing 1020 having an opening or series of openings 1001 for receiving up to six medical devices 1100, 1200, a sterilization chamber 1021 formed within the housing 1020 that is lined with sterilizing radiation reflecting material 1002, and several sources of sterilizing radiation 1003 disposed within the sterilization chamber 1021 for sufficient emission of radiation to achieve a significant log reduction of any pathogens present on the medical devices 1100, 1200, and an RFID scanner 1004 and sensor suite 1005 configured into the housing 1020 that prevents sterilization of non-system components, radiation emission into the environment, and that can pair with a user's mobile device.

In accordance with other aspects of the present invention, the opening of the device housing 1020 consists of a two-panel door 1006 that swings clear of the opening to facilitate easy access to the sterilization chamber 1021 housed within, which in turn features individualized trays 1007 specially configured to hold individual medical devices 1100, 1200 for sterilization. These trays 1007 can be individually rotated outwards to expose their contents for removal, access, and deposit as seen in FIG. 11 . In accordance with yet other aspects of the present invention, the door 1006 used to access the interior of the device 1000 comprises one quarter to one half of the overall surface of the device 1000 such that the user has greater accessibility to the individual trays 1007 when the device 1000 is open and will be able to remove or deposit medical devices 1100, 1200 more easily than a lid comprising only the front wall of the device 1000. In accordance with yet other aspects of the present invention, the door 1006 used to access the interior of the device 1000 may feature an embedded sealing gasket 1008 along the outer perimeter of the door 1006 that forms a hermetic seal with the walls of the sterilization device 1000 when closed, such that it is non-permeable by gas or liquid. In accordance with yet other aspects of the present invention, the closing of the door 1006 may initiate the beginning of a sterilization cycle provided that other requirements for the initiation of a sterilization cycle are met.

In accordance with other aspects of the present invention, the sterilization chamber 1021 formed within the housing 1020 may be lined with a sterilizing radiation reflecting material 1002 such as mirrored aluminum or PTFE to provide high reflection of any sterilization radiation that is not absorbed or otherwise attenuated by the medical devices housed within the device 1000.

The RFID module 1004 may electronically interface with the microcontroller and/or logic board that controls the emission of sterilization radiation into the interior chamber 1021 of the device 1000 for sterilization to prevent the emission of sterilization radiation if an individual has placed a RFID-embedded medical device 1100, 1200 that has been sterilized more than a pre-specified number of times. The RFID module 1004 may also electronically interface with a suite of sensors 1005 through a microcontroller and/or logic board to ascertain whether or not a medical device 1100, 1200 lacking an RFID 1101, 1201 has been inserted into the at-home sterilization and data acquisition and deposition device 1000, and the microcontroller may prevent the emission of radiation sterilization until the medical device 1000 lacking an RFID has been removed from the at-home sterilization and data acquisition and deposition device 1000.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may include a safety interlock mechanism. The safety interlock mechanism may consist of a Hall Effect sensor and a rare earth magnet, and wherein the Hall Effect sensor senses the magnetic field of the magnet when the access door 1006 is closed and sends a signal to the user interface indicating a ready state for the excitation of the radiation source 1006. The sterilizer circuit and microcontroller logic may utilize a sensor suite that includes but is not limited to hall effect, temperature, and pressure sensors to validate that the sterilizer is completely closed for the duration of the sterilization cycle, to prevent UVC radiation from escaping the sterilization unit. In accordance with yet other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may include an electronic safety mechanism. The electronic safety mechanism may consist of a suite of sensors 1005 that detect ambient temperature, light, and pressure within the sterilization chamber 1021, and transmits a signal to interrupt any on-going sterilization cycle upon detection of a dramatic change in readings throughout the course of the cycle. In accordance with yet other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may include a feedback loop that consists of a radiation sensor or suite of sensors placed in a hard-to-irradiate location within the sterilization chamber 1021, wherein the sterilization cycle continues so long as the sensor or suite of sensors has not registered sufficient radiation to kill pathogens that cause UTIs. In accordance with yet other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may include a feedback loop that incorporates one or more sensors to detect active and inactive cell population on a sampled point of the medical device 1100, 1200 before and after sterilization cycle is operated (e.g., cell detection method via camera or other sensor).

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may use an ultrasonic transducer (i.e., piezoelectric) used to transmit oscillatory ultrasonic waves into the interior of the sterilization chamber 1021. Ultrasonic waves are known as an effective tool to removing physical debris on solid surfaces and would be helpful in removing potential biofilm debris from the medical device 1100, 1200 before or during the sterilization cycle (e.g., ultrasonics).

In accordance with other aspects of the present invention, a micro fluid pump is used to pump fluid into and out of the at-home sterilization and data acquisition and deposition device 1000. In this embodiment, the fluid pump is used to pump a mixture of water, hydrogen peroxide, and silver particles to enhance sterilization. It is known that hydrogen peroxide and silver particles enhance DNA inactivation when using in conjunction with UV radiation. After sterilization, the micro fluid pump will remove remaining fluid within the sterilization chamber 1021. The micro fluid pump can either be included within a unit that is attached to the apparatus or integrated within the sterilizer device 1000. For example, the sterilizer device 1000 may have a port to connect to a fluid pump to provide fluid to the interior chamber 1021.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 further comprises one or more EMI shielding components or layers to protect electronic components.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may pair with an individual's mobile phone or personal computer or other such device to deliver usage statistics, detailed troubleshooting steps, status updates, as well as other data. This pairing may be further defined as enabling an individual to scan the RFID-embedded medical devices 1100, 1200 to verify their authenticity as well as observe the remaining number of sterilizations possible for the scanned devices 1100, 1200. This pairing may be further defined as enabling an individual to remotely control the at-home sterilization device 1000 through their mobile phone or personal computer or other such device.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may be configured to have a screen 1010 on the device 1000 in order to communicate to an individual using the device 1000 the current status of a sterilization cycle, or otherwise indicate the remaining longevity of the RFID-embedded medical devices 1100, 1200 that are being used in conjunction with and are being sterilized by the at-home sterilization device 1000. The remaining longevity of the RFID-embedded medical devices 1100, 1200 may additionally be communicated to an individual via RGB LEDs 1011 corresponding to each individual medical device 1100, 1200 located on the front face of the at-home sterilization device 1000.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may initiate a sterilization cycle when an individual presses a start button 1012 located on the front face of the at-home sterilization device 1000, and may prematurely end a sterilization when an individual presses a stop button 1013 located on the front face of the device 1000.

In accordance with other aspects of the present invention, the at-home sterilization and data acquisition and deposition device 1000 may be configured to vent heat generated from the electrical components and radiation emission sources held within through a series of vents 1014 located on the top of the device 1000.

The lubricant dispensed by the lubricant bottle may be further comprised of or be mixed with a pharmaceutical agent intended for reducing active pathogens post-sterilization (e.g., the device includes the ability to disperse pharmaceuticals on catheter as it lubricates). Alternatively, the pharmaceutical agent may be intended to counteract inflammation.

In accordance with other aspects of the present invention, the set of accessories to enable proper lubrication, cleaning, and radiation-based sterilization of medical devices 1100, 1200 may include a elongate silicone brush capable of dispersing chemical sterilizing agents in powder, gel, or liquid form while also abrading pathogenic residue and/or biofilms from the interior surface of an elongate, tubular medical device without causing damage to the interior surface of the elongate, tubular medical device.

In accordance with other aspects of the present invention, the RFID-enabled medical devices 1100, 1200 may be comprised of a set of mating stiff and flexible components that detach for easy cleaning, which are further comprised of components that intended for use outside of and inside of the body. These devices 1100, 1200 may include curved funnels 1105, 1205 at their distal end to facilitate the flow of liquid throughout the devices 1100, 1200 while minimizing the splashing of liquid. These devices 1100, 1200 may include stiff insertion aids 1106, 1206 that are adapted to male and female anatomy to provide structure and support during the insertion of flexible urinary catheters 1110, 1210, and which further provide a means of sterile lubrication, alignment, and insertion of urinary catheters 1110, 1210 into the urethral tract. These devices 1100, 1200 may include components that allow the devices to self-seal through the implementation of a quarter-turn luer lock or some other substantially sealing and mating mechanisms 1107, 1207 in the distal funnel 1105, 1205 and proximal insertion aid 1106, 1206 ends of these devices 1100, 1200, in order to allow individuals to carry these devices 1100, 1200 in transit without fear of leakage from the devices 1100, 1200 once they have been used.

The insertion aids 1106, 1206 may be further comprised of flexible bags 1108, 1208 that mate to both the catheter 1110, 1210 and the stiff components of the insertion aids via stiff collars 1109, 1209, therein providing a protective yet tactile barrier that allow individuals to directly manipulate the flexible catheters 1110, 1210 without contaminating them with pathogens. These devices 1100, 1200 may be made from materials with a high degree of sterilization radiation transparency such as polypropylene film. These devices 1100, 1200 may be engineered with additional reinforcing material in structurally vulnerable areas such as eyelets and joints in order to maximize their lifespan over a pre-specified period of use. These devices 1100, 1200 may be so engineered in order to be successfully reused and sterilized in the at-home sterilization device 1000 fifty to one hundred times each. These devices 1100, 1200 may be designed to maximize usability by individuals with limited dexterity through the incorporation of oversize tabs and other accessible features through their design.

In accordance with yet other aspects of the present invention, the individual catheterization system may include an electronic medical record or medical device distribution data interface that utilizes data gathered from the RFID scanner 1004 within the sterilization and data acquisition and deposition device 1000 in a HIPAA compliant manner and securely transmits it to various stakeholders in the healthcare ecosystem, including, but not limited to, urologists, occupational therapists, physical therapists, and medical device distributors. This data interface may further be comprised of an anonymization and aggregation of the data gathered from all deployed sterilization and data acquisition and deposition devices in order to analyze trends and correlations of catheterization practices and urinary tract infection incidence, and may further communicate to the user of such devices best practices for catheterization in order to avoid infections.

Specifically, the medical device 1100, 1200 may include or be a catheter. According to aspects of this invention, the catheter 1100, 1200 may be a urinary intermittent catheter, primarily fabricated from a UVC-transparent and flexible material 1110, 1210 with a stiff funnel 1105, 1205 fabricated from cyclic olefin copolymer or FEP, and intended to be inserted into the human body for 3-5 minutes at a time to facilitate the drainage of urine from the bladder into a receptacle. For males, the catheter 1100, 1200 may likely be between 11.5 and 12 inches long (not including the funnel, which is itself 1 inch long); for females, the catheter 1100, 1200 may likely be between 3 and 5 inches long (not including the funnel).

The catheter 1100, 1200 is tagged with an RFID chip 1101, 1201 that is scanned upon placement into the sterilizer 1000. The chip 1101, 1201 may contain authentication information [e.g. serial number] as well as usage information [how many times that specific catheter 1100, 1200 has been sterilized]. This information could potentially grow to include time and date of the last sterilization. This RFID tag might actually go on the insertion aid 1106, 1206 instead of on the catheter 1100, 1200 directly. The electronics suite of the catheter 1100, 1200 may grow over time to give the catheter 1100, 1200 the capability to perform real-time analysis of the bioburden present within the urine. Each of the electronic sensors used to perform this analysis would potentially store their readings in a separate RFID chip 1101, 1201 [e.g. an RFID array] or a single high-capacity RFID chip. The RFID tag 1101, 1201 present on the catheter 1100, 1200 may also be scannable by mobile app and mobile phone RFID reader to validate the number of uses left in the catheter 1100, 1200 or insertion aid 1106, 1206 and generally access the data remotely/in the absence of the sterilizer 1000.

The catheter 1100, 1200 may include many features related to reusability. For example, the catheter may include reinforced eyelets, such that the catheter 1100, 1200 may be reinforced with additional material around the drainage eyelets in order to withstand material fatigue over time. In another example, the catheter 1100, 1200 may include a reinforced mating area with the funnel 1105, 1205. The catheter 1100, 1200 may be reinforced with additional material around where it mates with a hard funnel 1105, 1205 to facilitate drainage of urine away from the body, in order to withstand material fatigue over time. The catheter 1100, 1200 may also be UVC transparent, such that all parts of the catheter 1100, 1200 may be made with UVC transparent materials that allow germicidal wavelengths of UV light to simultaneously sterilize the interior and exterior surfaces of the catheter 1100, 1200. The catheter 1100, 1200 may have a usage lifetime of as much as 100 uses each.

The funnel 1105, 1205 of the catheter 1100, 1200 may also include various features. For example, the catheter 1100, 1200 may include a curved funnel 1105, 1205 that reduces material strain on the catheter 1100, 1200 when stored in conjunction with the insertion aid 1106, 1206 and reduces the flow rate of urine exiting the funnel 1105, 1205 end of the catheter 1100, 1200 by virtue of increasing surface area contact between the funnel 1105, 1205 walls and the urine. Additionally, the distal end of the catheter funnel 1105, 1205 may include a quarter turn female luer lock component that mates with the proximal end of insertion aid 1106, 1206. This provides a substantially water-tight, air-tight seal. Additionally, this component can interface with a number of catheter product accessories such as a portable urine drainage bag or an adaptor that facilitates connection to a standard water bottle. The seal is substantially air- and water-tight, enabling a hermetic seal that allows for sterile transport of the insertion aid 1106, 1206 and the catheter 1100, 1200 once fully assembled.

Additionally, the proximal end of the catheter funnel 1105, 1205 may include a female mating interface that either accepts a snap fit or threaded male insert from the insertion aid 1106, 1206. This enables the insertion aid 1106, 1206 and the catheter 1100, 1200 to be disassembled for rinsing and cleaning. The seal is substantially air- and water-tight, enabling a hermetic seal that allows for sterile transport of the insertion aid 1106, 1206 and the catheter 1100, 1200 once fully assembled.

In another embodiment, the catheter 1100, 1200 may be include increased usability by people with limited dexterity. These catheter 1100, 1200 may include easy-to-grip plastic tabs and/or loops around each distinct component of the catheter 1100, 1200 such that a single finger can be used to disassemble or assemble the catheter 1100, 1200 and insertion aid 1106, 1206. Additionally, the catheter 1100, 1200 may be made out of biodegradable/compostable plastics.

The medical device and catheter 1100, 1200 may include an insertion aid 1106, 1206 as illustrated in FIGS. 13 and 14 . The insertion aid 1106, 1206 may include a stiff apparatus that mates with a flexible, thin plastic bag 1108, 1208 with threaded or snap fit collars 1109, 1209. The stiff apparatus provides support and lubrication to the catheter 1100, 1200 as it is being inserted into the body, while the flexible, thin plastic bag 1108, 1208 acts as a prophylactic barrier between the catheter 1110, 1210 and the human body, to reduce contact contamination risk at the moment of insertion into the body.

The insertion aid 1106, 1206 may include an insertion tip 1112, 1212. The proximal end of the insertion aid 1106, 1206 may include a flexible insertion tip 1112, 1212 whose inner diameter matches the French size of the catheter 1100, 1200, with a thickness between 5 and 10 mils [thousandths of an inch]. The tip 1112, 1212 acts as a prophylactic barrier between the catheter 1100, 1200 and the meatus of the urethral opening. The insertion aid 1106 may also include an usability handle 1102. For example, the male version of the insertion aid 1106 features a usability handle 1102 that can be used to support the insertion aid 1106 against the shaft of the penis throughout insertion. The usability handle 1102 may be designed so that one hand is sufficient to stabilize the insertion aid 1106, 1206 and catheter 1100, 1200 while the other hand is used to insert the catheter 1100, 1200 into the body.

The female version of the insertion aid 1206 may include a flange 1202 at the base of the insertion tip 1212 that female users can apply pressure to with their fingers to hold the insertion aid 1206 securely against the urethral opening. The flange 1202 has been designed to be compatible with the anatomical geometry of the vagina, and can be used to securely hold the insertion aid 1206 against the urethral opening while simultaneously spreading the labia apart for easier insertion of the catheter 1200.

The insertion aid 1106, 1206 may include a lubrication reservoir 1104, 1204 that can hold a predetermined amount of lubricant without leakage. For example, as the catheter 1110, 1210 is inserted into the body and travels through the reservoir 1104, 1204 and the insertion tip 1112, 1212, the catheter 1110, 1210 is coated with a thin layer of lubricant to facilitate insertion. The lubrication reservoir 1104, 1204 may be filled through a luer lock mating system, wherein the lubrication reservoir 1104, 1204 has a sealed female port that mates with a male applicator tip that screws onto a refillable lubrication bottle.

The insertion aid 1106, 1206 may also include a stiff insertion aid proximal interface 1107, 1207 that is located at the proximal end of the stiff insertion aid component and features a quarter turn male luer lock component that mates with the proximal end of catheter 1110, 1210. The seal 1107, 1207 is substantially air- and water-tight, enabling a hermetic seal that allows for sterile transport of the insertion aid 1106, 1206 and catheter 1110, 1210 once fully assembled. Additionally, the insertion aid 1106, 1206 may include a stiff insertion aid distal interface that is located at the distal end of the stiff insertion aid component and features a female mating interface that either accepts a snap fit or threaded male insert from the insertion aid bag. This enables the insertion aid 1106, 1206 and catheter 1100, 1200 to be disassembled for rinsing and cleaning. The seal is substantially air- and water-tight, enabling a hermetic seal that allows for sterile transport of the insertion aid 1106, 1206 and catheter 1100, 1200 once fully assembled.

The insertion aid 1106, 1206 may also include a collared bag 1108, 1208. A flexible component of the insertion aid 1106, 1206 may be comprised of a flexible plastic bag 1108, 1208 that is bookended by collars 1109, 1209 that are either threaded or have a snap fit feature on them to facilitate mating with and subsequent disassembly from the insertion aid 1106, 1206 and catheter 1100, 1200.

Additionally, the insertion aid 1106, 1206 may include increased usability by people with limited dexterity. For example, this increased usability may include easy-to-grip plastic tabs and/or loops around each distinct component of the insertion aid such that a single finger can be used to disassemble or assemble the catheter 1100, 1200 and insertion aid 1106, 1206.

The insertion aid 1106, 1206 may be RFID tagged with an RFID chip 1101, 1201 that is scanned upon placement into the sterilizer 1000. The chip 1101, 1201 may contain authentication information [e.g. serial number] as well as usage information [how many times that specific catheter has been sterilized]. This information could potentially grow to include time and date of the last sterilization. This RFID tag 1101, 1201 might actually go on the insertion aid 1106, 1206 instead of on the catheter 1100, 1200 directly. The electronics suite of the insertion aid 1106, 1206 may include the insertion aid 1106, 1206 with the capability to perform real-time analysis of the bioburden present within the urine. Each of the electronic sensors used to perform this analysis would potentially store their readings in a separate RFID chip [e.g. an RFID array] or a single high-capacity RFID chip.

The RFID tag 1101, 1201 present on the insertion aid 1106, 1206 may also be scannable by mobile app and mobile phone RFID reader to validate the number of uses left in the catheter 1100, 1200 or the insertion aid 1106, 1206 and generally access the data remotely/in the absence of the sterilizer 1000.

All parts of the insertion aid 1106, 1206 may be made with UVC transparent materials that allow germicidal wavelengths of UV light to simultaneously sterilize the interior and exterior surfaces of the insertion aid. The insertion aid 1106, 1206 may have a usage lifetime of 100 uses each.

The sterilizer 1000 may include a sterilizer interface. The sterilizer interface may provide a color-coded display for remaining uses. The sterilizer 1000 may inform the user how many uses is left in each catheter 1100, 1200 based on their relative position within the sterilizer 1000. For example, the status indicator may shine green if the catheter 1100, 1200 or insertion aid 1106, 1206 has been used less than 75 times each; yellow if the catheter 1100, 1200 or insertion aid 1106, 1206 has been used between 75 and 95 times; and red if the catheter 1100, 1200 or insertion aid 1106, 1206 has been used between 95 and 100 times. Other colors and usage times may be utilized without departing from this invention. The sterilizer 1000 may include an LED pixel matrix that visually indicates to the user how much time is left in the sterilization cycle.

The sterilizer 1000 may include various software features. The sterilizer 1000 may include an automated replenishment. For example, based on number of uses remaining in the plurality of catheters 1100, 1200 and insertion aids 1106, 1206 used with the sterilizer 1000, the system can automatically initiate a catheter reorder with the user's medical device distributor. In another embodiment, the sterilizer 1000 may include catheterization analysis. For example, the software may analyze the frequency of catheterization based on detection of catheter removal from the sterilizer [RFID reader scans the sterilizer interior every time the door 1006 is opened or closed] and frequency of sterilization cycles. In another embodiment, the sterilizer 1000 may include application pairing, where the sterilizer 1000 may pair with a digital application on a mobile device to provide more detailed status updates and diagnostics of the device 1000 to the user. The sterilizer may use data gathered from the application [UTI incidence, urologist check-ups, etc.] to augment its analysis of the user's catheterization data. In another embodiment, the sterilizer 1000 may include EHR integration to provide urologists with seamless, real-time updates on catheterization frequency and sterilizer analysis.

The sterilizer 1000 may also include portable, battery-powered sterilizer 1000 that primarily utilizes UVC LEDs to sterilize used catheters 1100, 1200 between uses. This portable sterilizer 1000 would likely have a carrying capacity of one catheter 1100, 1200 and insertion aid 1106, 1206 at a time.

According to another embodiment, a catheter scrubber may be utilized. The scrubber may be a 12-inch-long silicone brush that can scrub the interior of a catheter 1100, 1200 without materially damaging the catheter 1100, 1200 itself. The scrubber may be used to reduce biofilm/pathogenic residue on the inside surface of the catheter 1100, 1200. The scrubber may be coated or coatable with an additional disinfecting agent [powder or liquid].

The sterilizer 1000 may include a digital application for use with a mobile device. The digital application may be a companion application for the sterilizer 1000 that features added functionality for the user. For example, the digital application may provide on-the-go validation and usage information, such that the application can scan each catheter 1100, 1200 and insertion aid 1106, 1206 using the RFID/NFC technology in most mobile phones to validate authenticity and tell individuals how many uses they have left. In another embodiment, the digital application may include replenishment reminders and confirmation, such that the application can insert reminders in their calendar to re-order catheters from their distributor and update these reminders based on real-time usage of catheters. The application can additionally notify users of automated replenishment orders and ask for their consent before submitting the order for fulfillment. In another embodiment, the digital application may include location-based data gathering, such that using the application with location services enabled allows the application to ask individuals contextual questions. For example, if located near a hospital, the application may ask the user if they are experiencing UTI-like symptoms. Similar survey questions may be sent out periodically in the absence of location services to gather UTI-incidence data for analysis of catheterization habits and UTI incidence. The digital application may utilize anonymized data gathered across all users of the system and the application may suggest behavioral changes to limit UTI incidence.

In another embodiment, as illustrated in FIG. 15 , a method 1500 for sterilizing one or more medical devices using electromagnetic radiation may include the steps of: enclosing one or more medical devices in a sterilizer 1510; scanning, by an RFID scanner within the sterilizer, the one or more medical devices placed within the sterilizer to validate the authenticity of the one or more medical devices 1512; write, by the RFID scanner, data to an RFID chip embedded in each of the one or more medical devices 1514; sealing the sterilization chamber with a door that hinges open to allow individual access to the one or more medical devices 1516; starting a sterilization cycle with an internal control circuit for controlling the sterilization cycle with sterilizer software 1518; and irradiating surfaces of the one or more medical devices with electromagnetic radiation from at least one electromagnetic UV-C radiation source 1520.
